RIGID GONVEYER non mourns;

Specification of Letters Patent.

Patented July 20, 1915.

Application filed November 8, 1913. Serial No. 799,888.

To all whom it may concern:

Be it known that I, THOMAS M. Mounwoon, a citizen of the United States,and a resident of 135 Vestfield avenue, Elizabeth, New Jersey, and whosepost-office address is No. 253 Broadway, borough of Manhattan, county,city, and State of New York,

have invented certain new and useful Improvements for Rigid Conveyersfor Liquids, set forth in the followingspecification.

This invention relates to shipping packages or cartons for sendingliquids and semiliquids such as milk, cream, butter, cheese, jelly,honey, and the like by parcels post.

The objectv of the invention is to combine a plurality of structuralfeatures so as to produce at little expense a single unitary packageembodying indestructibility, hermetical inclosing, light weight,non-contamination of the substance contained and facility in packing.

Illustrative embodiments of the invention are shown in the accompanyingdrawings, in which like characters designate corresponding parts, whichform a part of this application and in which Figure 1 is a sideelevation with the ends in vertical section of one embodiment; Fig. 2 isan enlarged vertical section of the embodiment of Fig. 1 beforethe'outer shell has its end crimped; and Fig. 3 is a .vertical sectiongreatly enlarged showing a spring metal clip for clamping the cap.

An inner tubular shell 1 is built up out of paper or like substance byany well known process such as winding or folding several laps over amandrel. in any event tubular preferably greater in length than indiameter and may haw e any shape in cross-section but is preferablycylindrical. The stock of which the shell 1 is formed should besterilized and disinfected, which may be accomplished satisfactorily bysubjecting it to super-heated steam and the employment'of a suitabledisinfectant such as sodium and calcium hypochlorite which isnon-poisonous and leaves the shell odorless. In the formation of theshell 1 attention is paid principally to the production of a tough wallwhich will bend rather than crack. The inner part of this shell 1 isimpregnated and lightly coated with a lining 2 of a substance imperviousto the goods to be contained. Paraffin is suitable for this purpose. Theshell 1 may be dipped when hot in paraffin-or when hot This shell is themelted paraffin may be brushed or sprayed on. This lining 2 should bemore than a surface coating. It penetrates as well as coats the fibersat and near'the surface and fills all seams.

An outer tubular shell 3 is formed snugly v to it by friction or asuitable adhesive. This shell 3 is shown made up of spiral overlappinglays of cheap paper to make a shell of consid rable strength againstcollapse. It may have a thickness of wall much greater than that of theinner. shell 1. Its end rims l and 5 lap beyond the ends of the shell 1.

Disk-like caps 6 and 7 of sterilized and disinfected paper-board arestamped out so that their marginal contour corresponds to the outercross-section of the shell 1 and fits into the projecting margins 4 and5 of the outer shell. These caps (land 7 are lined and coatedinteriorlythroughout the entire extent of their inner surfaces as is theinner.

shell 1. The outer ends 8 and 9 of the shell 3 may then be crinip edinwardly against the caps 6 and 7 to clamp them to the ends of theshell 1. The crimping machine should heat the margins of the caps 6 andto melt and seal together the inner coatings 10 and 2, and 11 and 2 asshown at 12 and 13. Beadings 11 and 15 of sealing wax or parafiin may beapplied tothe joint between the crimps S and 9 and the caps (3 and 7. Inpractice the bottom cap 7 should first be applied. and clamped home. Thecarton is then filled and the top cap 6 is applied, sealed and clampedhome. It may be desired to omit the crimp 8 for the top cap 6 andsubstitute the clip 16.

This clip 16 is a sheet metal. ring bent at an to inclose the shell 1and may be secured angle 17 about the edge of the rim 4 and havingspursv 18 forced into the body of the shell 3. On the inner face of therim 4 this clip 16 has spring-fingers 19 sprung inwardly slightly. Thecap 6 should be of such a size as to be forced in past the fingers 19against the end of shell 1, where it is held by the fingers 19 whichhave sprung out to engage the outer face 20 of the cap 6.

l/Vhat is claimed and what is desired to be secured by United StatesLetters Pat-- ent is 1. A carton suitable forthe shipment of liquids andsemi-liquids comprising an inner tubular shell of paper; disk-hke caps ifor covering the ends of said inner tubular shell and having a marginaloutline corresponding to the uter cross-section of said shell; a liningo fi meltable material impervious to the substance to be containedcoating the inner face of said inner shell and the entire inner faces ofsaid caps, the said coatings being welded together by melt ing at theirmeeting localities, an outer tubular shell of paper-board snuglyinclosing said inner shell and lapping over the ends thereof; and meansat the end rims of said outer shell for clamping said ca'ps firmlyagainst the ends of said inner tubular shell.

2; A carton suitable for the shipment of liquids and semi-liquidscomprising an inner tubular shell of paper; disk-like caps for coveringthe ends of said inner tubular shell and having a marginal outlinecorresponding to the outer cross-section of said shell: a lining ofmeltable material impervious to the substance to be contained coatingthe inner face of said inner shell and the entire inner faces of saidcaps, the said coatings being welded together by melting at theirmeeting localities, an outer tubular shell of paper-board snuglyinclosing, said inner shell. and lapping over the ends thereof; andmeans at the end rims of said outer shell for clamping said caps firmlyagainst the ends of said inner tubular shell, said means at one endcomprising an in ward crimp of the end rim of said outer shell.

3. A carton suitable for the shipment of liquids and semi-liquidscomprising an inner tubular shell of paper; disk-like caps for coveringthe ends of said inner tubular shell a nd having a marginal outlinecorreshell; a lining of material impervious to the substance to becontained coating the inner faces of said inner shell and said caps; an

outer tubular shell of paper-board snugly inclosing-said-inner shell andlapping-over the ends thereof; and means at the end rims of said outershell for clamping said caps firmly against the. ends of said innertubular shell, said means at one end comprising an inward crimp of theend rim of said outer shell and at the other end a marginal metallicclip having inwardly directed spring fingers yielding upon the seatingof said cap later to spring out to hold the rim of said cap.

'4. A carton suitable for the shipment of liquid and plastic materials,comprising an inner shell of tubular form, a gjslg s eparate from saidshell and disposed iiarallel with and in close proximity at one endthereof, a lining impervious to the material to be shipped and engagingthe inner surface of said shell and covering one face of said disk, saidlining being provided with a peripheral portion of annular formextending between the periphery of said disk and the adjacent end ofsaid tube, an outer shell encircling said inner shell, and means carriedby said outer shell for engaging said disk and pressing the same towardthe adjacent end of said inner shell.

In Witness whereof, I have signed my name to this specification, in thepresence of two subscribing witnesses.
